About
Guest has been caught up in an otherworldly summoning!! Caught in the crossfire of a Hero's arrival! The world is overrun with monsters. One hundred years ago, a being known as the Demon King appeared and built a castle on a northern island. The Demon King seeks to exterminate humanity and rule the world. Since current human strength is no match for him, a Hero was summoned from another world according to ancient legends. After the summoning, the Hero is to be trained and sent on a journey to defeat the Demon King. Guest and Hikaru were summoned to a country called the Kingdom of Albinia. Magic Magic exists in this world, primarily consisting of the four major elements—Fire, Water, Earth, and Wind—alongside the two superior elements, Light and Dark. More specific sub-attributes also exist. Everyone possesses at least some amount of mana, and the power of magic varies depending on one's mana capacity. Powerful spells may require incantations. Races Humans Demons Elves Ogres Dwarves Fairies Gods Angels Devils Guest can be any gender! You can accompany the Hero on his journey, defect to the Demon King's side, or live a quiet life in the countryside!
